To all whom it may concern.-

Be it known that I, ANDREW D. ERIoKsoN, a citizen of the United States, residing at l/Villiston, in the county of Williams and State of North Dakota, have invented certain new and useful Improvements in Photographic Apparatus, of which the following is a specification.

This invention relates to photographic a paratus and the object thereof is to provide a substitute for the ordinary form of dark room utilized to develop plates, films, or the like, for placing the plates in plate-holders, and in similar operations.

The invention comprises portable means readily adapted to be carried in a satchel, trunk, or the like and comprising a base on which the apparatus for developing or conducting similar operations may be placed, said base being used to sup ort an enveloping hood for the operator, said hood providing a darkened compartment when in position, and this compartment is adapted for all of the uses for which a dark room is ordinarily employed.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings, in which- Figure 1 is a perspective view showing the apparatus embodying the invention, the hood being open preparatory to receiving the body of the operator. Fig. 2 is a perspective,

view of the apparatus in operative position, the hood being partially broken away to show the interior arts. Fig. 3 is a perspective view of the ase and the supportingstandards thereon. Fig. 4 is a perspective view of the base collapsed.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring to the drawings, the numeral 1 designates the base, and the same is preferably made of sections hinged together at one end, as shown at 2, so that the base may be reduced to a comparatively small size to take up a minimum amount of space when the apparatus is not in use. The outer end of each of the sections of the base 1 has a transverse cleat 3 at its upper side, and these cleats are formed with vertical openings adapted to receive the lower ends of standards 4. The standards 4 are removably arranged on the base 1 when in position, and said standards are preferably made of telescoping parts adjustable for pur oses hereinafter set forth.

The darkene compartment necessary in the use of the apparatus is formed by an enveloping hood 5, which may be made of any material preventing the penetration of light, black cloth being preferably utilized. The hood 5 is in the form of a sack or bag and is adapted to receive the base 1 therein, said base being arranged so that the standards 4 Will hold the upper portion of the hood above the base and ermit free manipulation of the ap aratus, w 'ch may be carried by the base.

n the practical use of the invention it is preferred that when the same is used in a dwelling the base 1 be disposed on a table or like support within the hood 5. The standards 4 are placed in position so as to hold the hood up from the base, and the operator may be seated on a chair with the u per portion of his body received in the hood at the open end thereof. The open end of the hood will be provided with a drawstring 15, which can be readily grasped by the operator and tied, so as to tightly secure the hood to his waist and prevent all likelihood of light getting into the com artment which is darkened by the use of said hood. It will be obvious that the apparatus may be readily used when the operator is working out of doors, as the same may be readily set up and will be convenient to admit of quickly placing plates in plateholders and accomplish similar operations, such as are-necessary when the ordinary dark room is not accessible. The hood 5 is preferably rovided at a side thereof with an opening clbsed by transparent material, as shown at 6, preferably of red color, and this opening admits light in the darkened inclosure, said light being of such a nature as not to injure the plates on exposing the same and offering the same facilities as the ordinary photographic lam The simp icity of the apparatus of setting the same up and collapsing the same is obvious and needs no further description.

Having thus described the invention, what is claimed as new is- In photographic apparatus, the combination of a base comprising sections hingedl connected at one end and adapted to be disposed flat against one another, transverse cleats applied to the onter end of each sec- In testimony whereof I affiX my signature tlon, vertlcal openings 1n said cleats, vertical in presence of two Witnesses. standards havmg the lower ends thereof re- ANDREW D- ERIOKSON.
